The Monticello House in Virginia was built in 1772, and is Thomas Jefferson's burial site. You can see the house on the US Nickel. It was a working plantation where he kept many slaves.
Toward the end of his life, it's believe he wanted to end slavery. In 1779, Jefferson supported gradual emancipation, training, and colonization of African-American slaves instead of unconditional freedom, believing that releasing unprepared slaves with no place to go and no means to support themselves would bring misfortune upon them.
“Some people believe Jefferson wanted to end slavery.”
